Products Description
Product Definition
The Nexisense SMP6387 viscous liquid special flat diaphragm pressure transmitter is a high-precision pressure measurement device specifically designed for measuring pressure in complex media containing mud and sand. This product utilizes advanced sensor technology and reliable electronic circuit design to provide stable output signals in harsh working environments.
Working Principle
The working principle of the SMP6387 pressure transmitter is based on the piezoelectric effect and current signal conversion. Pressure acts on the diaphragm, causing deformation that changes the internal electrical signal of the sensor. This signal is processed and converted into a standard 4-20mA current output, facilitating compatibility with various control systems.
Structural Analysis
The structure of the SMP6387 includes the following main components:
Housing: Made of stainless steel, providing excellent corrosion resistance and mechanical strength.
Sensor Part: Utilizes 316L stainless steel to ensure durability in complex media.
Sealing Ring: Made of fluororubber to ensure sealing under high pressure.
